TO ADL- WHOM IT-MAY CONCERN:

Be it known that I, ABNER BASSETT, of the city of Virginia, county ofStorey, State of Nevada, have invented certain new and usefulimprovements in\Afmalgamators for working gold and silver-bearing oresand extracting the' precious metals, called Bassetts Ama-lgamatorg and Ido hereby ldeclare the-following description and accompanying drawingsare suliicient to enable any person skilled in the art or science towhich it most nearly a'ppertains, to makel and use my said inventionwithout further invention or experiment.

The nature of my'invention -consists of a barrel or other suitablevessel, with a hollow shaft passing longiv tudinally through the centre,by which heat is introducedby means of exhaust steam, or otherwise; thebarrel or cylinder being inclosed in a shell or bath whereby hot air isintroduced aroundv the entire circumference of the barrel, aswell asthrough the centre. The 1pulp not coming in contact with the steam,important chemical `'changes are electedby the heat in itself. Inthedrawings- `Figure l is a side elevation. I

'a a a, stuffing-boxes; b, pulley by which the machine is driven; c,hollowshai`t, open at both ends, for introducing the steam pipsd ZZ', dbeing the induction pipe, and d' the escape pipe. e is Aa barrel orother shaped suitable vessel, constructed of iron or other suitablematerial, through which the hollow shaft c passes; the shaft beingconstructedl tight, so as not to admit the steam or heat directly intothe pulp or ore to be amalgamated, but imparts its influence uponv theouter circumference of the barrel or vessel which contains the pulp'. fis a man-hole'of barrel; y, discharging pipe. The outside shell or bath,hin which the barrel is revolved, is formed in halve-s, coupled togetherby'means of lanches and bolts. z' z" are steam pipes; z' is theVinduction pipe,` z" the escape pipe. J J are hatchways on the outsideshell, .used principally 'or'testingv and discharging the ore or pulp. 4The whole being mounted upon some suitable frame, the shell resting uponpins placed at suitable distances around the inside of the frame. Bythis arrangement it is not intended that the shell shall revolve,but-remain stationary, enclosing the barrelthrough which the hollowshafl't or cylinder passes, causing it to revolve `by means ofthe pulleyb.- The ore to be amalgamated is placed -in the barrel with the usualaccompaniments well known to metallurgists, when the steam or heat isadmitted through the hollow shaft, and into the shell through the pipez', and the barrel slowly revolved until a complete amalgamation iseipecteil. By this arrangement of introducing steam or lient, both on orthrough and around the pulp, without coming-in direct Contact with it,great beneficial chemical changes are produced, generating gases, andcausing a separation of' metals from o bdura-te ores, which isindispensable for :i free amalgamation.

Ha'ving thus described m v invention, I will now proceed to 'state whatI claim, and desire t0 secure by Letters Patent; that is to say, I donot claim the use oi' steam For amalgamation of ore.

l What I claim, is

1., The barrel e or its equivalent, having a hollow shaft,'c, passingthrough it, by which heat is introduced y by exhaust steam or otherwise,substantially as described and for the purpose setforth. l '2. I claimthehot-air shell or bath g, i'or the purpose of .applying heat, byexhaust steam or otherwise, t0 v the out-side of the vesselcontainingthe pulp, whereby obdurate ores are made to amalgamate morefreely, subl stantially as described, and for the purpose specified. I i

3. I claim the application of steam or heat to the ore or pulp, boththrough and around it, without coming in direct contact with itl.; thesaid ore or pulp being confined in some suitable vessel, said vesselheingenclcsed in a shell or bath, for the purpose herein set forth.

In witness whereof I have hereunto set my hand and seal this 16th day ofAugust, A. D. 1866.
